cross-weave mechanism for power-looms by means of which certain novelelfects in weaving can be'produced on power-looms which have heretoforebeen producedon hand' In our automatic cross-weave mechanism l certainwarp-threads are taken while the shed lto-form the top ofthe shed.lterns all thewarp-threads would be used, some in crossing .over andforming the botis pforming by needles which extend directly in front ofthe reed and have forked or twopronged ends and carried across in groupssimultaneously over adjacent groups ot' warpthreads and then carrieddown between they warp-threads to form the bottom of the shed, 'whilethe. remaining warp-threads are raised In certain pattom shed and theothers in making the top'of the shed; but this is not necessary. We canVuse a limited number of warp-threads in the cross-weave, andthe rest ofthe warp-threads linev 1 1, Fig. 2,

can be-used in Weaving the fabric in the ordinary way.

A needle-,barg20 carries in this instance a series ofdownwardly-extending needles 21,

which may be' adjustably attached at their upper end's to the lower partof the needlebar by screws 21 or otherwise, and the lower engaging ends'of they needles are made forked orwith two prongs, (see Fig. 4)-thatis, with open eyes forthe free entrance of the warp-threads which are tobe Atransferred inf. stead of with closed eyes through whicl thewarp-threads are threaded, as is customary inlappet and other similarlooms. .The nee.V die-bar 20 has in thisA instance .at each endY abracket 20'. thereon and a set-screw 20"', by

` which passes through a hub 24 on said arm 24.

On the outer end of one of the bars 22e-in this 'instance on theright-hand end of the loom, (shown .in Fig. 1)-is fast angleLiron 26,carryinga stud 2.6', on which is mounted a roll'27. The lroll 27 bearson a cam-surface,

'(see F ig.f6,) which controls the transverse motion given to theneedle-bar 20, carrying the vneedles 2L, which needles engage thewarp-threadsl and carry theml across the adjacent warp-threadc.

' Wewill now describe the mechanism for producing the transverse motion'of the needle-bar and needles, as desired.

A jack 28 (see Fig. l) has one endof Aa connector 29 attached theretoand the other end 'of said connector attached to one arm of thebell-crank lever 30, pivoted at 30' on the loomarches B. The other armofr the h.ell-crank vlever 30 is attached to one end of a connector 3l,which passes under a roll 32, mounted on 'a stud 33 oma stand 34,sec'ured to the loom side.

It will be seenA thatrwhen the jack 28 `is 4raised the ratchet 40willbe turned one tooth `bythe pavvll 39 through intermediateconnections, andthe cams 4l vand instance oneQeighth of a revolution.The pe- 45, which bears on a Vend with ribs or tins 56" The other end ofsaid connector 3l is'; attached to the outer end of a horizontalV le-2.)

The lever 44 has theslot 44"Lin its (See free end, in which is supported'. toextendgjv downwardly, asshown in Figs. 4 and 5', a' stud flange or disk 45; fast on' a rod 47."he inner -end of the rod-47 .is s'ecured to a guide-plate 48, and theother end of the rod 47 extends through an arm of the.

stand 43 and has a collar 49 fast on its end,

.between which and the stand 43 extends an expansionspring 50, mountedon. the lrod 47, which springv acts to hold the flange or disk 46 incontact with the stud 45 and the; rounded extension 44 in contact withtheperiphery of the cam 4l.4 The guideplate` 48 has secured theretoneareach end the inner ends of two guide-rods 5l, which pass throughthe'arms on the stand 43. Said rods 5l hold and guide .the plate 48v asit is moved toward the lay through the cam 4l, lever 4.4', and roll 45,en-

gaging the iiange' or disk 46 on vthe rod 47, se-

cured to said plate 48 and moved away from the lay by the spring 50..The periphery .ot' the cam 42, which extends below the' cam 41 and' isfast on the shaft 36, bears against the lrounded extension 52. onthelever 52, pivotally mounted on the stud.44..in the stand 43. Thelever 52'has a slot 52.',(see Fig. ,63) for adjustment of the engagingbar 53 securedto the lever 52 by la bolt 53. The bar 53 has a rounded4extension 53", which 4bears against the flange or disk 54, fast on therod 55, which rod has attached to' its in ne'rend the camplate-56.y jl57, secured .to the stand 43, and has an expansionespring 58 thereon,confined between the-collar 55 and the bracket 57. y (See Fig. 4.)

'lhe cam 42,rotating onV the same shaft and at the same time as cam-41, controls theposition of the cam 56 relative to the guide-plate 48, and thereforedetermines the amount of travel of the needle-bar 2O transversely to thewarp-v threads. By virtue of the slot 44 inthe 1eoted on stud 44, (see'Fig'. 6,) adjustment is4 `cam 56.

At the same time the adjacent groups of warp-threadsnot carried down are raised, in the lmanner to befherein-v afterdescribed, to form the .whole or part of the uppershed, according to thenumber of needles .and the nature of the pattern.

. We willL now describe the mechanism forv carryingf the needle-bar 20andneedles 21A downward into the warp after they have beenmovedtrausversely, as above described.-

One end .of a connector 60 is attached to Va jack 28 and passesover therollsl and 62, -mounted between the loom-arches. `Theother end of lsaidconnector 60 vis attached to oneend of a centrally-pivoted lever 63..(See Figs. 3, 7, 8,"and 9.) The le'ver 63 is vpivoted `on a stud 64 oua stand 65,l fast o na cross-girth 66. On the opposite end of the lever63 is fast a pin 63', whichv extends into aslot 67 in the lower end Iofan upright rodl 67, whereit is held in the position 'shown in Fig. 9 byatension-springv 68, conneetedat one` endtothe lever 63 and at itsotherend Ato the'` Hoor, as

` in ,the lower end .of the collar 73 on the lower shownin Fig. 9.' Arock-shaft 69 is Kmounted in bearings 70, secured tothe lay-swords, and'has fast thereon thev rocker-arm 7l,`inthe vo'uter forked end of which'extend the ends of thepin 7"., free to movefina horizontal slotImmediately the needleshave gone their distance transversely they arecarriedv forming part of our improvements.

end of the vertically-moving rod y25, which entends through and `has;'bearings 23 inthe 4guides (SeeFig. 7;) The supportingarins 2.4#of theneedle-rod bars 22 are fast on the rods'25. In its normal position theneedle-- bar 20 i-s held up by the action yof the spring 68. When it isdesired to lower the ncediebar 2O and needles 21, the jack 28, to whichthe connector 60 is attached, is raised'to roel:

the lever 63, and the pin 63' will have a down? ward movement in theslot 67 in the bar 67. In the upper end of the bar 67is securedl thelower end of the upright bar' 75, and the `up- .per,end of'said bar 75has the end 75' thereon pivotally attached by the pin 75" to thearnnWhen the pin l 63' moves downward in the slot 67 in the'v bar 67as abovestated, the needle-bar 2O 7,6, fast on the rock-shaft 69.

and needles 21 by force of gravity, assisted by the spring 78, fast tothe lever 63` and to thel end 75 on the rod 75, are 4brought downwarduntil the roll 79 on the 'stud 79 in the slotted end 80 of the arm 80,fast on the rock-shaft 69, comes in contact with the camplate 81,secured to the inner side of the loom side. On the forward stroke. ofthe lay the roll 79 travels on cam-plate 8l, as shown in.

Eig. 8, and raises the needle-bar 2O and the needles A21, and onthe'backward stroke of the lay the roll 79, traveling on the cam-plate 28l,4 determines the amount of` downward` movement of the needle-bar 20and needles 21. When the jack 28, to which the connec tor'6'0 isattached, is dropped, the spring 68 acts to move the lever 63 andthrough pin 63 raise the bar 67 and rod 75 and through arm 76 rock theshaft 69 and raise the needle-bar 20 and needles 2l.

We will now describe the harness-inotion In cross-weaving the crossingover of the warp-threads cannot begin until thev shed has openedsuiiicientlyfor the needles toengage their respective groups of.threads. The adjacent groups which are to form the top of the shed muststay down until the crossing over has taken place and mustthen bebrought up 4behind the needles which have just crossed over above them.This opera tion-requires time, and it will be seen that at one time inraising certain warp-threads in the ordinary formation and at anotherTIO .certaiuharnesg frames which areengaged 90and 91) in the slot 94 ofthe (lobby-frame. .(See Fig. 1.) The knife-bar 93, which isindependently drivenby a crank (not shown) on a revolving shaft oftheloori1 ,is carried 5 outan'd back in its slot 94 while the knifetroplete movement.

bars 90 and 91 "are making theirtravel inv one direction-that is, theknife -bar 93' makes two complete lmovements out and in while' theknifefbars'QO-and 91 are making one com? A hook-leverl 95, pivoted onthe end of a lever-95", pivotally mounted on anextensio'non'l a jack,will when raised,

l`4 as shown in Fig. .1, engage the knife-bar 93 fand through theintermediate connections known Way, except that the-raising` of thejackis delayed and takes place in -half the time ordinarily required.

The harness-framel, Fig. 1,'is one of 'the 2o frames requiring twoindependent motions.

Connectors 9T are attached at one end to a jack 93, connected with thedobby mechanism,` and pass over rolls 99 and are connected at theirother ends to the u'pper part of the l:harness-frame I to raise saidframe in the orgo' of the sheave 102 and on opposite theharness-frame I,

iinary way. One end of another.. connector 100 is attached atone end toanother jack 'and at its otherend to an offsetspoke 101 on the: pulleyor sheave 102'. To the peripherysides of thefsame 'are fast the ends ofthe connectors 103,` vwhich are guided by flanges on the sheave '102vand pass over grooved pulleys "1:04, mounted in brackets 104', andthence to4 cured'. Springs 103 nectors103 intermediate the harness-frameI and the pulleys 104, as shown in Fig. 1.

It Willbe seenl that when the harness I is 4o fcalle'd by the jack 98finthe ordinary way the connectors the harness-frame I will hang slack, theslack being-taken-up by the springs 103. After Vthe -crossingfoverprocess above describedan indication is made for the raising of th-eharness 1 through' the movement of the knife-l bar 9 3 and intermediateconnections to` the harness, during which time lthe connectors l97 willhang slack. Thus the twoindepend- 5b ent motionsof the harness Irequiredby the vour easing mechanism,

3, 10,. and -11 ofthe drawings; ',On the nature of the weave .areprovided for.

It is necessary'that the crossover-threads have a slackening or easingmotion yduring the crossover process. We will'now describe which shownin Figs.

nections gives anup-and-down motonsto the.

plate 118 at everypick of the loom. ``l:'-Sup'- ported in suitablebearings attached to the stands 1 19 at the -rearof the loom are tworock-shafts 120,V and 121, 'having thereon sleeves 122 and 123.'Fastfto. the shaft 120 is the..lever1.24,"having at .its free .end anotched extension 124'-, extending under the ,plate11Sz (See Fig. 10.) Alever 125, centrally pivoted on the end of the lever 124, is notched ateach end, as shown at 125 and 125". A spring 126, attached at lone endtothe upper part 'of the lever 125 and at its othervend to the lever124, acts .to hold the lever 125 in the position'shown in Fig. 3, whichis in its normal position when'the easing motion is not in use.

A connector 127 is,l attached at one end to the lower part Vof the leverand vpasses over a' grooved roller 128 on the lever 124 and is connectedat lts end to one arm of an angle-lever 129, pivoted vat 130 in a standv131. The other arm of said ang-le-lever'130 is-connected through the'connector 132 with one arm of an angle-lever 133, (see Fig. 3,) and theother arm of said angle-lever 133 is connected by a connector (notshown) with a jack (not shown) ofthe dobby-'rnechan-ism. It will be seenthat the movementvv of the dobby-jack through intermediate connectionswill movev the lever 125 against the action of the spring 126 to causeits upper lnotched end'125' to extend over the plate'118,`as showninFig. 10,

and the raising of the rodll and the plate said shaft, to be carriedtoward the front of the loom, as 'shown' in' Fi'g.'10 thus producing thedesired slack in the Warp-threads. The operation of the easing-rod 135at the lower end of lthe'arm 13S, fast on the rod 121, which lhasa lever139 fast thereon and a lever to correspond vwith the lever 125,.moun,tedon the end of said lever 139," is the same as the operation oftheeasing-rod '135, above 4 described. lO n each rod 12-0 and 121is asleeve 122 and.- 123, respectively, with levers correspending to tthe-lev'ers 124 and,139"and arms Ico i corresponding to the arms 134and'138, as

shown in Figs. 3 and 11. The sleeves 122'and 12'3`are freetorotate onthe rods 120'and-121.

There'are four sets of intermediate connec--- v tions4 between the fourmechanismv and fou-r jacks of the dobby `mechlevers of the easing IIO `Q l', and over vthe easing-rod 135 and through the'harnesses (notshown)-to the f ell of. the fabric in the' usual Way..` The 'rocking ofthe shaft 120, above described, by the raising of the lever 124 causesthe easingrod 135, connected'with anism. The plate 11S' on the rod 116,which rises-:and 'tails at every pick,`lrises freel unless one ot'. the'four levers 125 is called through i intermediate connections by itsdobbyjack... On the return or downward motion of theA lever 124,y andthe lower notches 125' on thelevers corresponding to levers 125A willengage the bracket 117, asshown in Fig. 3,*to prevent the operation ofthev easing motion due to the strain on the warp-threads. The stop-.rod141 limits the downward vvmovement. ofv

the levers. l.

XVe will now describe the modified construction of the dobby and harnessjack mechanism, which modied construction is shown in Figs. 12 and 13 oflthe drawings.. In these i ligures we have shown the pattern-surface andintermediate connections between the pattern-surface and the hookedlevers for operating the same tocause them to'be engaged lwith ordisengaged from Vthe knife-bars 90 and 91, which are operated in theusual way. The pattern-barrel 202 carries the pattern-chain 203, made upof links and bars carrying pegs or pins. VEttendingoverthepattern-chainisaseries of weighted levers 204, pivoted at 205 and whichhave the forked branches 204' and 204". 'lhevbranch204 engages the lowerhooked lever"9`5 and the branch 204" engages the lower end of theupright wire 206, whose upper end engages the upper hooked lever 95. Thestand 209 is fast to the (lobby-stand and has bearings thereon-'for thetransverse shaft 210. Loosely mounted on said shaft 210 are thecentrallypivoted levers or supplemental jacks 211, to the lower end ofeach of which is pivotally attached the inner end of the lever 212.' Theouter end of said lever212 is slotted` or grooved to ride on the outerend to be engagedby the knife-bar 93. A stopbar 213, forming upper partof comb, prevents 4,the ,lever 212 from being thrown up out ofengagement with the hook-lever 95. i A coil n51o spring 214, attached atone end to the lever 211 below its pivotal support and at its other endto astationary part of the frame, operates' to hold the lever 211 andthe lever 212 intheposition shown in Fig. 12. The upper end of eachlever211 passes through an elongated slot in a loop 216, which has avpinor stud/,217, which engages the u pper end of the harness-jack 218, asshown in Fig. 412. `To

the opposite end of.V the loop 216 is attached the end of a connector(not shown) toa h arness-frame in theordinar'y way. When the jack 218 ismoved to the left, Fig.f12,the'loop 210 ismoved tothe left, as shown. bydotted lines,- Fig. 12, without moving the lever211, the groovcdfend ofsaid lever'preventing` the loop from falling oit ofl tlie-.lever`211.,When

the lever 211is moved byengager'nentofthe knife-bar 93 with the lever212, as shown in Fig. ,13, the loop 216 is also-,moved by engagement ofthe lever 211 with pin 217 in 'loop 216 without'inoving the jack 218,and through a.

connector (not shown) the harness-frame con nected'with said loopismoved. The patteruchain. as shown in Figs. 12 and 13, operates to holdthe hooked levers 95 and the lever212 in three different positions.`When there is no indicator-pin under the lever 204, the hooked leverv95 and the lever 212 will occupy the position shown in Fig. 12, withthe lever 212 in position to b'e engaged by the knife-bar 93. When *ashort. indicator-pin 220 comes under the lever 20.4 to raise it, it willlower through intermediate connections the two hooked levers 95 and thelever 212 to an intermediate A or an inoperative position, so that theknifebars and 92 and-the knife-bar 93 will move in `and out withoutengaging either of said hooks or the lever 212. When a long`indicator-pin 221'comes under the lever 204, it will raise it to itshighestposition and through intermediate connections lower the hookedlevers 95su1liciently to permit of engagementwith the knife-bars 90 and91 and also lower the lever 212 to aposition out of engagement with itsknife-bar93. '[he knife-bar 93 is operated when desired, as shown inFigs. 1,2 and 13, to

raise the harnessV attached to the loop 216 at a higher speed than isobtained with the jack 21S, while the beginning ofthe movement to raisesaid harness is delayed for the purpose heretofore described withreference to the harness-motion shown in Fig.` 1.

In Figs. 14 to 19, inclusive, we have shown a modified construction ofthe needle-bar 20. (Shown in Fig. 1j.) In the modified constructioninstead of 'having'a single needle-bar we have two parallel needle-bars230 and 231. Oneneedle-bar, as 230, is fast to an angle-iron 232,thesame as in Figs. 1, 4, 5, 'and 6, above described. 'Phe angle-iron232'has a hub-like extension 232', iuwhich is fast a sliding rod or bar22, corresponding Lo the bal-22 in Figs.

A16 and 17, \vi'th.hublike exteusions`233, is

of the latch' 235 and the other'end bearsv against the needle-bar 231.v(See Fig. 17. The `lower hooked endl`23" of thela'tch 235 extends underand engages the underside of the offset 232"l on the angle-iron 232,fasshown in Fig. ,14, so that normally the twoneedle-n desired acts throughintermediate connections and the connector 241 to draw down the Iarm ofthe-angle-lever 239, to which it is attached, and cause the rod 240 toextend under the hook 235' on the latch 2,35. (See Fig. 15.) As the twoneedle-bars 230 and 231 start to move down,l operated in the same manneras above describedin connection with the needle-bar 20, the engagementof the rod 240 with the hook end-235' kof the latch l235, as abovedescribed, moves the latch 235 on its .pivotal su pport againsttheactiou ofthe spring 236 and disengages the lower end 235 from theoffset 232 on the angle-iron 232, leaving the needle-bar 230 free to belowered,'while the needle-bar 231 remains in its raised position, heldup by the engagement of the hook 235 of the latch 235With the rod 2&0,as shown in Fig. 15. It will be understood that the rods 233 and240extend transverselyacross the loom, and there is a correspondingl latch235 at the opposite 'end ofthe loom. (Not shown.) On the return`movement of the needle-bar 230 to its highest position the upper sideof the extension 232'", Fig. 17, on the plate 232 strikes against thelower edge of the plate 233 and raises said plate 233 and the needle--bar 231 and allows the spring 236 to move the latch 235 to the positionshown in Fig.14. Meanwhile a' spring (not shown) operates to move theangle-lever 239 and carry the rod 24:0 out of engagement with the hook235 of the latch 235, as shown in Fig. 14. A stop 24:2 on the rod 238engages the upper surface of the latch 235, as showxrin Fig. 14, and

' prevents the needle-bar 231 from being carried 'up above a desiredpoint. Each' needleb ar 230 and 231. carries a series of separateneedles 244:, each of which in this instance is secured in a separateholder 213,- which, is.

supported on the needle-bars by means of extensions 2lf3 between whichthe needle-bar die-bar 231.l One or more'of the needle-hold.-

'ers 246 will be placed near the center of the needle-bars'to steady andkeep the two sets of needles in proper alinement.

A series of pins 217 extend vertically through the lay, Figs'. 14 and15, and are automatically raised at every pick to serve as a guide forthe flying shuttle and as a protection to the forked needles 21 in theusuall way.

It will be understood that the details of construction ot' ourimprovements maybe varied, if desired, and .we do not limit ourinventionto the particular mechanism shown-l in the drawings and describedherein.

We are not aware that prior to our invention needles extendingdirectly'in front-of the reed and having forked or two-pronged ends haveever been used in automatic crossweave looms to engage certain of theWarpthreads which :are free of the needles until engaged and then by thelmovement of the.'
